:3 Claims. l1(Cl.-339'-220) This invention relates in general tonew and useful s. 2,929,045 Ptented Mar.^v, -1960 .lfor attachment to an electronic instrument chassis and vat the other end with an attaching flange, the terminal being attached to the base by means of prongs struck out p from the terminal, the formation of the prong resulting 'in the formation of openings, one of the openings in the terminal being disposed at an intersection of the flange 'with the remainder of the terminal to form a wire receiving socket in the flange, there being mounted onthe i support a first velectrical component formed of relatively described and claimed, reference being had toV the" ac- .improvements in electronic parts, and more specifically "instrument However, these terminals are relatively small small wire and attached to the 4attaching -iange,there also being a second electrical component such as av relatively l'arge'wi're which is received in the wire socket.

These together with other objects and advantages which *will become subsequently apparent 4reside in`the details of"construction and operation as more fully hereinafter companying drawings forming a part hereof, wherein "like numerals refer to like. parts throughout, and' in "which:

Figure 1 is a sideelevational view of a coil which employs the terminalv to base connection which is the subject of this invention, the coil including a coil component and a resistor;

. and in many instances'it is necessary toconnectfwires of V'relatively great size thereto. "This isfp'articularly'ftrue in the instance of resistors and Ithe like. In order-to `hold the wires in place, it is normally necessary to twistr them aboutlthe-terminal. Because of the relatively large di- Lameter of the wiresand the st'ilfness thereof, this is'a J difficult operation and is not only time consuming, b'ut 'oftentimes results in the damaging 'of the terminal. `Also, 'in certain instances it is necesary to attach both fine wires and relatively thick wires to the same terminal. TThe fine wire in many instances must be attached first "Iandthe thick wire afterwards. "In the attachment of ."thick wire the fine wire is oftentimes broken.

.'It'is therefore the primary object of this inventionto ""provide an improved terminal to base connection which "is 'ofV Vsuch a nature whereby there is automatically formed "a wire socket Vfor receiving and holding 'in frictional contactwith the terminal a relatively large cross-sectional rwvl/1re.

v'Another object of this invention is toprovide an irn- "proved terminal to base connection which includes a ter- "mi'nal having 'prongs struck therefrom, the prongs being `p`as'sed into the base to 'secure the terminal inplace, the formation of the prongs resulting in openings -in the terminal, the openings being exposed in overlapping rela- "tion'to theends of the base whereby there is provided "sufficient space for the passage of the wire to be conynected to the terminal.

-Still another object of this invention is to provide `an "improved terminal and base construction for electronic parts, the terminal being secured to the base by means Lof prongs struck therefrom, the prongs leaving openings in the terminal, the terminal being provided with a wire `Vattaching ange which is connected to the remainder of *"the terminal intermediate the ends of one of the openings, *the portion of the opening disposed-within the attaching Figure 2 is a top Aview of the coil of Figure 1 and "shows further, the details thereof;

A further object of this inventionis to provide' an'relec- `'tronic--part lwhich includes' a support," a haseonthe supporti'andf-"at. lea'st one 'terminal Icarr'ie'd by f the-base, *the rsternrinallbeing providedfatone endthereof-i withmeans 'and themanner in which the wires of the'electrical components areA attached thereto;

Figure 5 is a fragmentary plan view similar to Figure 2 yand shows the manner in which additional wires may be attached to the terminal; and

Figure 6 is an enlarged fragmentary longitudinal sectional view taken through the electronicpart of Figure -l and shows the details of the relationship between a terminal thereof, a base thereof'and wires connectedto the terminal.

Referring now to the drawings in detail, it will be seen that there'is illustrated in Figures l through 4, inclusive, a 'preferred electronic part which is referred to in general by the reference numeral 10. `The electronic `part `1.0 is in the form` of a coil and includes a tubular support A -`12 which has a base 14. The tubular support 12 and the base 14 are preferably formed of an insulating material and may be integrally molded or may be in sepa- Arate parts with the base 14 telescoped over the supportlZ.

In order that the base 14 may be connected to a printed circuit board or the like and at the same time complete `the electrical connection between the electronic part 10 and the printed circuit of the printed circuit board, there -is carried by the base 14 a plurality of terminals 16.

-vEach of the terminals 16 is formed of lan elongated strip of material and includes a bodyr portion 18 which terminatesvat its lower end in an ofisetmounting'portion Z0 which is used to secure the terminal 16 to a'print'ed circuit board (not shown) and form an electrical contact rbetween the printed circuit thereof. The opposite end 'of the body portion 18 is in the form of an outwardlydirected attaching flange 22.

Referring now to Figure 4 in particular, it will vbe seen that there is struck from the body portion 18 a pair of prongs 24 and 26. The formation. of the prong 24 re- 1sults in the existence of an'elo'ngated opening 28 in the `rllower part :of the :body portion 18 while the Aformation `otttheprong -26 results in the' existence"of"an"elongated opening 30 in the upper part of the body portion 18. The terminal 16 is so secured to the base 14 whereby the opening 2S overlaps the lower end of the base 14. The opening 30 is so positioned whereby the connection between the attaching flange 22and the base portion 18 is disposed intermediate the ends of the opening 30. Inasmuch as the opening 28 extends below the lower end of the base 14, thereV is produced a wire socket in the terminals 16 between the terminals 16 andthe base 14. Also, the opening 30 is Vso located with respect to the attaching flange 22 that there is disposed in the attaching flange 22 a wire socket 32, which is best illustrated in Figure 3, the wire socket extending along the exterior surface of the base 14,

Wound upon the terminal support 12 is a coil 34. The coil 34 includes a wire 36 which is of a relatively small size. The wire 36 is wrapped around the attaching ange 22'for mechanical securement thereto prior to the soldering operation. As is best illustrated in Figure 3, each attaching flange 22 has Side edges in which there are formed wire receiving notches 3S which slope away from the wire socket 32. Thus when an end of the wire 36 is wrapped about the attaching flange 22 in the notches 38, the wire 36 is urged away from the wire socket 32.

Disposed about an intermediate portion of the coil 34 is a protective strip 40. Engaging the protective strip 40 is a resistor 42 which includes connecting wires 44. The connecting wires 44 are of a relatively large crosssection as compared to the wire 36 and cannot be easily i bent, about the terminals 16 for attachment thereto. However, the wires 44 are of a size to be snugly received in the Wire sockets 32 of several of the terminals 16. This is best illustrated in Figure 3. Inasmuch as the ends of the wires 36 are spaced from the wire sockets 32, it will be seen that there is no interference between the wires 44 and the ends of the wires 36 so that the wires 36 are not actually broken. On the other hand, a single soldering operation may result in the forming of a solder drop 46 which will retain in place both the wire 44 and an end of the wire 36, as is best illustrated in Figure 4.

Referring now to Figures and 6 in particular, it Will be seen that there is illustrated a slightly modied form of an electronic'part which is referred to in general by the reference numeral 48. The electronic part 48 is almost identical to the electronic part and includes a tubular support 50 having mounted on the lower end thereof a base 52. Connected to the base 52 is a plurality of the terminals 16. The electronic part 48 also includes a coil 34 and a resistor 42. The electronic part 4S differs from the electronic part 10 only in that the base 52 is much shorter than the base 14.

Referring now to Figure 6 in particular, it will be seen that the length of the base 52 is such that the terminal 16 extends both above and below the base 52. The opening 2S overlaps the lower end of the base 52 to form a wire socket 56 which is identical with the wire socket formed between the opening 28 and the base 14. The opening 30 also results in the formation of the same type of wire socket 32. However, the attaching flange 22 is now disposed at the upper end of the base 52 and the wire socket 32 is disposed at the upper end of the base 52.

The wire 36 of the coil 34 is wrapped about the attaching flange 22 in the same manner as described above with respect to Figures l through 4, inclusive. On the other hand, the wire 44 of the resistor 42 in lieu of being passed down parallel to the base 14, as is illustrated in Figure 4, is pushed through the wire socket 32 up adjacent to -the attaching flange 22 so as to facilitate the positioning of a solder drop 58. Other wires 60 are passed through the wire sockets 56 and secured to the terminals 16 by a solder drop 62.

From the foregoing description of the present invention, it will be seen that the openings formed by the prongs of the terminals and serve the useful purpose of 4 forming mechanical connections between wires and the terminals prior to the forming of solder joints thus eliminating the necessity of bending heavy wire about the relatively weak prong.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and de scribed, and accordingly, all suitable modifications and equivalents may be resorted to, falling Within the scope of the invention as claimed.
